Sane, thats a great question you asked, which forced me to go back to basics. Why only Kerala got hit this hard and not other places in India? Surely we have hot-pockets all across the country but why only Kerala? So, this is what I conclude, see below and tell me if my logic makes sense.

What causes rain? answer: When warm air rises to the sky and cools down, water droplets form. When the cloud can no longer hold that moisture, rain fall occurs.

Next, Why certain regions get more rain than others? Answer: In order for the rainfall to happen, you need to have enough humidity/ moisture in the air. You get these more so from the ocean/sea than rivers/lakes. You will have plenty of moisture from rivers/lakes too but not as much as the ocean.
So, this air when it moves over the water bodies, it collects the moisture. As it rises high, it cools down and the moisture condenses into clouds/rain. usually the cooling process doesnt happen right away. However, when the moisture-filled-air moves upwards a mountain top, it cools down much much faster. So you can expect to see a lot of rain when you have sea and mountain in the equation.

Why Kerala? My answer: Kerala's geography is a perfect place for plenty of rainfall. It has Arabian Sea on its border (coastal area) giving moisture to the air. It has its Western Ghats consisting of high mountains, deep gorges etc cooling the moisture filled air from the sea a lot faster.
Now, kerala is naturally prone to landslides, erosion etc When you add illegal constructions along the mountain edge, you opened yourself up for more landslides.
Also, the way I see it, there is a lot of rain but this is not the only issue. The issue was that, there was no proper drainage into the sea. Most of the rivers seems to be choked with sand/sleet making the rivers less capable of holding the water. So when rainfall happens, it cannot hold it and the flooding occurs. That is why you HAVE to protect the river beds. I have said this before also, that Cochin airport is a prime example. They took a riverbed causing the river to have even less space to flow and drain into the sea.
Do no construct buildings where agricultural land should naturally exist. the land cannot take the burden, it gives in when the cyclones/ monsoon's start.

And another thing is, you cannot take over the mountain slopes, cut them and use for living. I understand there are poor people but if you dont understand nature, it is going to cost lives. a lot of them.
When you cut the slopes, the natural support is lost. When it rains, the landslides start.

What can be done? My answer: Assuming my logic is somewhat sound, I would start with cleaning the choking points of the rivers that drain into the sea. take steps from there on. Stop the illegal constitutions, dont play around with mountain, canals etc.

The entire state was besmirched with this disease and the gods did their best to eradicate it. Now we just have to wait and watch... for the results.

this is probably more complicated that simple logic on how rains happen and more simple than dont play around with mountains etc at the same time.

While the rain logic is more or less correct, it does not take into account how seasons work and how monsoon arrives in India - from the seas into the land, therefore Kerala is one of the first pieces of land in the path of monsoon.

what should have been better managed, knowing monsoon and with sophisticated meteorological tools now available, as you have suggested before, start opening the dam doors little by little and earlier - as cordinated activity across all dams in the region. For a country which manages to send 100+ satellites on a single launch vehicle, it should be possible to manage the water levels in the dams.

things like allowing rivers to flow, prevent illegal mining are basic things which should be done irrespective of flood situation.

this is probably more complicated that simple logic on how rains happen and more simple than dont play around with mountains etc at the same time.

I agree. But in order to understand what happened, I had to start over. Thats why the basics. I would love for you to elaborate more on the monsoon cycle. Not the google version, but a small "your" version.

My version is based on articles and news I have read over the past few weeks - so, no escaping google version.

crux is - Kerala has 40+ Dams, many of which were full or near full just before monsoon arrived. When monsoon came, it should have been BAU to analyse the situation with the Dams and let out some water.

Thank you, teacher. But you really think that this kind of rational and logical reasoning will change my pessimistic, bigoted, parochial, prejudiced, narrow-minded perception of real-life

Like many dams in India, the Mullaperiyar is located in one state (Kerala), but operated by another (Tamil Nadu). Both state governments have been in constant conflict over the damís water levelóin the current crisis, the Supreme Court had to intervene.
